WHAT IT DOES

What base_branch does on GitHub

AI agents call base_branch as a supporting operation in GitHub workflows.

RISK

Why base_branch is rated Low

The description reads like a parameter definition rather than a standalone tool. It specifies a string input for a branch base, with no described action or side effect of its own. Confidence is low because the description is uninformative as a tool definition. Classifying as Other since no actionable behavior can be determined.

From the tool's definition Tool description says 'Starting point for the new branch (optional) (string, optional)' — this appears to be a parameter descriptor, not an actual tool with its own action.

RECOMMENDED RULE

The rule that runs base_branch safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For base_branch, this is the rule to start with:

base_branch Rate-limited

base_branch gets a rate cap, and everything else on the server is denied unless you say otherwise.

SET A RULE FOR THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every base_branch call is checked against it from then on.
